Antelope Environmental Monitoring Software

Data Collection and Analysis

Antelope is an integrated collection of programs for data
collection and seismic data analysis, and typically runs at the
central processing site.
It has been in development for over a decade and is deployed around the world.

Near-real-time Processing

The Antelope real time system
is built around a large, flexible, non-volatile
ring buffer. Data acquisition modules communicate with data loggers, and leave
data on the ring buffer.
The ring buffer protocol provides a convenient
method for directly importing data from other sites, as well as
exporting data.
Real time processing typically occurs on the ring buffer: programs
take input from the ring buffer and write results to the ring buffer.
For instance, the detector reads data from
the ring buffer and writes detections to the orb.
The grid associator reads the detections and quickly provides preliminary
event locations.
This architecture facilitates running multiple detectors or associators,
and other refinements.

Open Architecture

Antelope runs in a UNIX environment
on Linux X86, Linux X-Scale, and Macintosh OS X.
Antelope has an open architecture, with extensive documentation of
internal interfaces. There is already support for
many common dataloggers and sensors, but other dataloggers, sensors, and novel
devices may be integrated by the end user.

Integrated Database

A relational database
underlies Antelope real time processing. Waveforms,
detections, events, and other data are saved from the ring buffer into the
database. The analyst reviews data in the database, and there are
database versions of programs
corresponding to the real time processing software.

Development Environment

Antelope is a development environment. There is extensive
documentation, allowing development of specialized software for
site specific applications. Languages supported include C, Fortran, Perl, TCL/Tk, and Python.
The Antelope Toolbox for MATLAB is also included for locations that have
MATLAB installed from The MathWorks, Inc..
The Antelope Users' Group
has collected source code generated by the Antelope User Community.
